What is the difference between open and closed section …

WebWith torsional loading, there are two types of sections, open and closed. An I-beam is an example of an open section and the tube is a closed section. Obviously there can be combinations and modified versions of both. Closed sections are preferable for torsional loading because there is a very clear path for the shear stress to flow in. http://dir.cisc-icca.ca/files/technical/techdocs/updates/torsionprop.pdf long term stay air b n b
